===NC200===
An upgraded version, the ''NC200'', appeared in late 1993, featuring a 3.5" floppy disk drive able to read/write MS-DOS-formatted double density disks, 128 KB RAM, some extra software - most notably a spreadsheet and three Tetris-like games - and a larger, backlit screen. However, this change required much greater power use, using 5 C cell batteries. The disk drive could only be used at near full-charge, which meant that it could only be used a few hours after putting in new batteries. However, the laptop could function for considerably longer than this without using the disk drive. The backlight can be manually toggled off to save power by pressing the Control and Caps Lock keys at the same time.
